Spring Weed Control: How to Stop Weeds Before They Take Over

Hi friends, I’m Alice! A chocolate lab who loves sunny sniffing walks, long naps in the fresh air, and rolling around in a soft, green lawn. Spring is my favorite season—not just for playtime, but because it’s the perfect time to keep weeds from taking over your yard! Those pesky dandelions and chickweed can sneak up fast if we’re not careful.

At Welch Lawn Care, spring weed control is one of the most important steps we take to set lawns up for a healthy, thick, green season—especially here in New England, where winter can leave lawns tired and patchy.

When Should You Start Weed Control?

Timing matters! In Southern New Hampshire, it’s usually best to start between mid-April and early May, once the snow has melted and the soil has dried enough to walk on without leaving footprints. Starting too early can damage soft turf, and waiting too long gives weeds a head start.

Pre-Emergent Herbicides: Stopping Weeds Before They Grow

A pre-emergent herbicide is a lawn’s first line of defense against spring invaders like crabgrass. Applied early, it prevents weed seeds from sprouting, giving your grass a head start. Be sure to follow label instructions and water lightly after application to activate it.

Spot-Treat Existing Weeds

Some weeds survived the winter—no worries! A targeted post-emergent herbicide can remove dandelions, clover, and chickweed without harming your grass. For smaller lawns or sensitive areas, manual removal is also a great option.

Healthy Grass Means Fewer Weeds

Strong, thick grass naturally crowds out weeds. Regular mowing, proper watering, and a spring fertilizer tailored for New England lawns help your turf grow dense and resilient. The healthier the grass, the harder it is for weeds to take root.

Spring weed control lays the foundation for a beautiful lawn all season. If you’re unsure when or how to start, don’t worry—the team at Welch Lawn Care is always happy to help keep your yard weed-free and ready for sunny days!
